Description

A kind of preparation method and applications of water-resistant type paper surface sizing agent
Technical field
The present invention relates to paper surface-sizing agent field more particularly to a kind of systems for the paper surface sizing agent that water resistance is strong Preparation Method and application.
Background technique
Cypres are the sizing agents for being applied to Paper or cardboard surface, its addition can improve page characteristic or increase paper Or surface property, intensity and the water-resistance of cardboard.
With the improvement of living standards, requirement of the people to paper quality is also higher and higher, while the development of society is to making The requirement of paper environment is more and more harsher, because of the research and development a bit to related papermaking chemical product and using more stringent requirements are proposed.Surface Most of sizing agent mainly consists of two parts: having the hydrophilic group structure of compatibility to the resistive hydrophobic group of water and to paper pulp At.When glue application solution is applied to paper surface, a part of surface size infiltration fills the gap in page in paper layer;It is another Part will stay on paper surface.In the drying process, since polymer shows as thermoplasticity, such polymer particle can be in paper Surface extension is opened to form one layer of continuous film, to improve the performance of paper.
CN104592448A discloses a kind of preparation method of Cypres, and deionized water is added in four-hole boiling flask And amylase is added after being warming up to 70-90 DEG C in starch, stirring, is continuously heating to 90-100 DEG C, and bicarbonate is added after keeping the temperature 1hr Then sodium, ferrous sulfate, glacial acetic acid start that monomer is added dropwise, dropping temperature is 85-95 DEG C.It is kept the temperature again after monomer dropping 1hr。
CN107142785A also discloses a kind of cation surface sizing agent and preparation method thereof, utilizes cation denaturation Acrylyl oxy-ethyl-trimethyl salmiac, acrylamide, benzene second is added as emulsifier in starch, polyvinyl alcohol and span-60 Alkene, butyl acrylate are copolymerized to obtain bronzing cation surface sizing agent.
Two kinds of Cypres are synthesized in the prior art above, the two uses starch or modified starch as dispersion Agent, and be to be directly added into monomer in monomer dropping mode.Use starch as dispersing agent its glue application solution storage stability not Height, while it is weak with paper pulp fiber binding force compared to macromolecule emulsifier, water resistance is poor.And it is directly added into the mode of monomer Often make emulsion particle diameter larger, while distributivity is wider.This makes in the more difficult gap for penetrating into fiber of emulsion particle.
Summary of the invention
In order to overcome the defects of the prior art, the present invention provides a kind of Cypres of water-tolerant and its preparations Methods and applications use emulsifier-free emulsion polymerization during synthetic surface sizing agent, do not dissociate in such system small Molecule emulsifier substantially increases its water resistance.Monomer is added dropwise by the way of first emulsifying monomer simultaneously, what is obtained in this way applies Glue partial size is smaller, and dispersibility is single, and such latex particle can be penetrated into preferably in fibre gap, improve itself and paper The combination on surface, to can also improve its water resistance.
To achieve the above object, the present invention adopts the following technical scheme:
The first purpose of the invention is to provide a kind of preparation methods of paper surface sizing agent comprising following steps:
Step (1), by part macromolecule emulsifier, (methyl) styrene, (methyl) esters of acrylic acid mix monomer, go from Sub- water mixes strong stirring, is prepared into lotion;
Polymer electrolyte emulsifier, the water of remainder are added to the container by step (2), are added and are drawn after being heated to 80-90 DEG C Send out agent;
After step (3), the lotion of step (2) reaction 10-20min, start to lotion obtained in its a dropping step (1), Time for adding is 1.5-3.0hr, cooling discharging after the reaction was continued 1.0-2.0hr.
In order to advanced optimize above-mentioned preparation method, the technical measures that the present invention takes further include:
Further, the container of the step (2) is any suitable reaction vessel in this field, preferably four-hole boiling flask.
Further, the method for lotion is prepared in step (1) are as follows: 500-800rpm is stirred after macromolecule emulsifier, water is added Mix, after slowly sequentially add (methyl) styrene, (methyl) acrylate, mixing time 30-40min.
Further, the macromolecule emulsifier of the total dosage 80wt% of Zhan is added in step (1), then in step (2) Remaining macromolecule emulsifier is added.
Further, the initiator can be added at one time in step (2), and one can also be added in step (2) Part, remaining part of then slowly dripping in the polymerization reaction of step (3).If initiator is divided into two parts addition, The initiator of the total dosage 30wt% of Zhan is at least added in step (2), remaining initiation then is added dropwise in step (3) polymerization process Agent.
Further, in the preparation method, including following component and its parts by weight:
Further, the paper surface sizing agent further includes suitable water, and water is for dispersing each component, this field skill The needs that art personnel can easily actually use according to product, adjust the dosage of water.It is preferred that 500-890 parts.Certainly, according to production The needs of product actual use, can also be added suitable quantity of water in inventive formulation to adjust the solid content of final products, such as can be again The water of 300-1200 parts by weight is added.
Further, the macromolecule emulsifier is selected from polyvinyl alcohol, polyethylene glycol, fatty alcohol polyoxyethylene ether, polyethers Polyalcohol, polyvinylpyrrolidone, alkyl phenol polyoxyethylene ether, aliphatic acid polyethenoxy rouge, fatty amine polyoxydivinyl ether, polyoxy At least one of ethylene alkylamine, polydimethyl diallyl ammonium chloride.
Further, described (methyl) acrylic ester monomer is selected from methyl acrylate, ethyl acrylate, the positive fourth of acrylic acid Ester, isobutyl acrylate, tert-butyl acrylate, Isooctyl acrylate monomer, Tert-butyl Methacrylate, isooctyl methacrylate, N-propyl, cyclohexyl acrylate, lauryl acrylate, 2-Hydroxy ethyl acrylate, 2-hydroxypropyl acrylate, first At least one of base methyl acrylate.
Further, the initiator is selected from dibenzoyl peroxide, peroxidized t-butyl perbenzoate, two laurel of peroxidating Acid, potassium peroxydisulfate, ammonium persulfate, hydrogen peroxide, tert-butyl hydroperoxide, sodium peroxydisulfate, hydrogen peroxide-iron sulfite, sodium peroxydisulfate- At least one of sodium sulfite, sodium peroxydisulfate-sodium hydrogensulfite, sodium peroxydisulfate-sodium hypophosphite.
Further, the solid content of the Cypres of this method preparation is 25-30wt%, pH 3-4.
A second object of the present invention is to provide a kind of paper for surface sizing of water-resistant type as made from above-mentioned preparation method Agent.
Third object of the present invention is to provide a kind of application of above-mentioned paper surface sizing agent in paper for surface sizing, Specifically by the water-resistant type Cypres, according to mass ratio 0.7-1.2:100, (the two is with the oxidized starch after gelatinization Oven-dry weight) compounding obtain glue application solution, be used for paper for surface sizing.
Compared with prior art, the present invention has the following advantages and beneficial effects:
In the preparation method of water-resistant type Cypres of the present invention, using emulsifier-free emulsion polymerization, while using will Monomer, which first emulsifies the mode being added dropwise afterwards, can increase substantially the effect of top sizing, and the Cobb value of paper is greatly reduced.This be because For using emulsifier-free emulsion polymerization, stabilizer of the macromolecule emulsifier as glue application solution greatly reduces and dissociates in emulsion system Small molecule, to improve the water resistance of paper.It drips after monomer is emulsified simultaneously, it is recognised that closing after partial size is tested At milk particle partial size it is lower, and dispersibility it is more uniform, this, which allows for latex particle, can preferably penetrate into the gap of paper fibre In, the binding force of latex and paper fibre is improved, so that the water resistance of paper is also improved.
